Abstract: A process for the preparation of ss-ionone by the sulphuric acid-catalysed cyclisation of pseudoionone in a two-phase solvent system consisting of concentrated sulphuric acid and an essentially water-immiscible second solvent is described, which process is characterised by the use of liquid carbon dioxide under pressure. Inter alia, this process is carried out under a pressure of about 50 bar to about 150 bar and, before the subsequent discontinuation (quenching) of the cyclisation reaction, at temperatures from about -15@C to about +15@C. The process according to the invention is preferably carried out continuously and is an important intermediate stage in the synthesis of vitamin A.

IPC: B60P1/48
Filed: 1977-12-23
Abstract: A continuous machine for the manufacture of fiber-containing materials such as paper, which comprises a rotating cylinder partly immersed in a body of liquid containing fibers in suspension. The surface of the cylinder comprises permeable and impermeable areas arranged in a predetermined pattern, and fibers are drawn onto the permeable areas by suction from within the cylinder, the layers of fibers formed on these areas being transferred to a conveyor belt which contacts the cylinder surface at a zone out of contact with the liquid. The surface of the cylinder is washed upstream of the transfer zone to remove fibers and other particles which may adhere to the impermeable areas of the cylinder surface by feeding cleansing liquid, such as pure water, across an overflow edge into a space adjacent the cylinder so that the cleansing liquid flows parallel to the impermeable areas.
Patent JP-H082519-B2 (JP)
IPC: B30B11/00
Filed: 1990-06-13
Abstract: The invention relates to a method and an apparatus for making dimensionally stable pressed articles from pulverulent compositions, in particular metal powder, on a press in a compression mould with at least one upper die and at least one lower die, in which the pressing dies in the final pressing position are moved to predetermined theoretical positions, and, during the pressing, the progression of the compressive force of at least one of the dies is recorded as a function of the travel and compared in each case with a predetermined, travel-dependent tolerance range for the compressive force. In order to provide a method and an apparatus which permit even closer tolerances as regards the dimensional accuracy of the pressed articles and at the same time further reduce the risk of defective production, it is proposed that, if the tolerance range is exceeded, the theoretical position of the die in question in the final pressing position is modified so that the height of the pressed article in the final pressing position is reduced by an amount which corresponds to the increased upward expansion of the pressed article after its unmoulding, associated with the higher final pressing force, and the reverse procedure is adopted if the compressive force falls below the tolerance range.

Patent JP-H0639259-B2 (JP)
IPC: B62D5/06
Filed: 1984-08-13
Abstract: A load sensing hydraulic system is disclosed which essentially eliminates kickback from a feedback mechanism contained in a manually operable control valve which in turn is fluidly connected to a hydraulic function. The system includes a power on demand pump fluidly connected between a reservoir and the control valve for supplying pressurized fluid to the hydraulic function. A load signal line is also connected between the control valve and the pump which serves to transmit pressure signals, which are generated by loads acting on the hydraulic function, to the pump for controlling the pressurized output thereof. A load signal control valve is positioned in the load signal line and is fluidly connected to the discharge side of the pump. The load signal control valve is capable of sensing pressure variations between the fluid discharged by the pump and the upstream fluid present in the load signal line. As soon as the control valve senses that the pressure of the fluid discharged by the pump is less than the upstream pressure of the fluid in the load signal line, it moves to block off fluid flow from the hydraulic function and thereby eliminates kickback on the manually operable control member.

Abstract: A new apparatus for turning up and down spectators' seats for a telescopic seating system of the type including a plurality of movable platforms which are arranged in tiers is disclosed. The apparatus essentially comprises a frame fixedly mounted on a movable platform, a foot member fixedly secured to the housing of a seat, a stopper link turnably supported on the foot member, an unlocking member turnably supported on the frame and a leaf spring operatively connected to the rear end of the stopper link. The foot member is formed with projections at the rear end part thereof which are adapted to abut against a front nose of the adjacent upper movable platform as the first-mentioned movable platform is displaced forwardly to the extended position. The foot member assumes the upright standing position by turning up on the frame together with the housing of the seat. The foot member is kept in the upright standing state while the stepped portions on the stopper link are engaged to the rear ends of the stopper pieces of the frame. As the movable platform is displaced backwardly to assume the retracted position, the inclined surface on the unlocking member abuts against the front nose of the adjacent upper movable platform whereby the stopper link is released from the engaged state and the foot member is then caused to turn down under the effect of resilient force of the leaf spring.
